THERMAL EXPANSION

The linear expansion of a heated solid or liquid can be measured by a quantity a, the coefficient of linear expansion. This coefficient is defined in such a way that it measures the percentage change in the length per degree temperature change.

Pengembangan linear bagi pepejal atau cecair yang di panaskan boleh disukat dengan a, , iaitu pekali pengembangan linear. Pekali ini di takrifkan sebegitu rupa dimana ianya mengukur peratus perubahan panjang bagi setiap satu darjah perubahan suhu.
